BIOS USER’s GUIDE

The system configuration information and chipset register information is
stored in the CMOS RAM. This information is retained by a battery when
the power is off. Enter the BIOS setup (if needed) to modify this information.

The following pages will describe how to enter BIOS setup, and all about
options.
